Abstract: MALFUNCTION DETECTION SYSTEM FOR A     PROGRAMMABLE CONTROLLER                            Abstract of the Disclosure A programmable controller includes a hardwired monitor module which connects to the I/O address decoder and the central logic unit of the controller. The monitor module detects malfunctions which cause deviations in the operation of these elements from a prescribed pattern, and in response generates a disabling signal which deenergizes all operating devices on the controlled system. A diagnostic module is also included and is comprised of a set of routines stored in the controller memory which periodically direct the controller to operate according to a prescribed pattern and to indicate deviations from that pattern as a malfunction. Such malfunctions are indicated in a diagnostic register which connects to the monitor module.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method of manufactur-ing a macromolecular form of active substances with -NH2 groups which is useful for protracted release of the active component by an enzymatic cleavage, wherein an N-substituted amide or ester of acrylic or methacrylic acid, which contains at least three chained atoms in its side chain terminated by the carboxylic car-bon atom, is condensed with the.alpha.-amine group of an aminoacid of L-configuration, as .beta.-phenylalanine, tyrosine, tryptophan, lysine, arginine, glycine, alanine, leucine, citrulline or ornithine, and then an active component is bonded by its -NH2 groups to the car-boxylic group of this amino acid and the resulting monomer is copolymerised with a hydrophilic monomeric component based on N-alkymethyacrylamide, N-alkyacrylamide, N,N-dialkylacrylamide where alkyl has 1 to 6 carbon atoms and may contain 1 to 3 -OH groups, or glycol methacrylate or glycol acrylate, where glycol is ethylene glycol, propylene glycol, butylene glycol, diethylene glycol, triethylene glycol and tetraethylene glycol, alone or in a mixture, and if desired with further monomeric components which may act as crosslinking agent.  The polymeric form prepared by the method according to the present invention enables to control the physical and biological fate of the active substance by the nature and molecular weight of the carrier-polymer.

Abstract: CONTROL LEVER ASSEMBLY FOR POWER SHIFT   TRANSMISSION AND MODULATING CLUTCH                   ABSTRACT OF THE DISCLOSURE            The power train of a crawler tractor comprises a hydrau-lically operated modulating main-clutch (operated by a clutch con-trol valve) for transmitting motive power from the tractor engine to a hydraulically operated reversible multi-speed range power shift transmission (operated by a shift selector valve) for varying the speed at the output shaft of the transmission.  A con-trol lever assembly at the tractor operator's station comprises a manually operable gear selector lever and a manually operable safety lever.  The gear selector lever is pivotally mounted on an oscillatable shaft and movable laterally in opposite directions from a centered neutral position to rotate the oscillatable shaft and thereby operate the shift selector valve (connected to the oscillatable shaft) and shift the transmission to either first or second speed ranges in either forward or reverse direction.  The gear selector lever extends through a slot in a U-shaped bracket which is mounted for fore and aft pivotal movement and is con-nected by specially-shaped cam means to operate the clutch con-trol valve.  The gear selector lever is also pivotally movable fore and aft in any selected speed range to effect corresponding fore and aft movement of the bracket and thereby operate the clutch control valve to cause transmission output shaft speed to vary in the speed range selected.  An adjustable friction assembly imposes drag on the gear selector lever to provide control "feel" for the operator.  The safety lever is pivotally mounted for fore and aft movement between engine-start and engine-run position and, when placed in engine-start position, actuates an electric safety switch which enables the tractor engine to be started.  Interlock means connected to and between the gear selector lever and the safety lever ensure that the safety lever cannot be placed in engine-start position unless the shift selector lever is placed in neutral.

Abstract: ABSTRACT OF THE DISCLOSURE              The invention provides a purge unit for establishing a closed zone for an inert gas around a weld area. The purge unit is particularly adapted for use where a branch pipe is welded to a main pipe or header. The purge unit is inserted into an opening in the header and is then expanded to establish the closed zone around the inside of the weld area. An inert gas, in a volume much less than otherwise required, is then supplied through the unit into the zone to cover or blanket the inside of the weld area. After the weld is complete, the purge unit can be collapsed and withdrawn through the opening so as not to leave any material within the header which might cause contamination.
